无法创建自定义视图的动画

Question

我正在尝试使用以下代码(来自苹果自己文档的objective-c的最佳翻译)来为我的自定义视图的移动提供动画效果。

        var animDict = new NSMutableDictionary ();
        animDict [NSViewAnimation.TargetKey] = this.View;
        animDict [NSViewAnimation.StartFrameKey] = NSValue.FromRectangleF (this.View.Frame);
        animDict [NSViewAnimation.EndFrameKey] = NSValue.FromRectangleF (new RectangleF (0, 150 * index, 400, 150));

        var theAnim = new NSViewAnimation ();
        theAnim.SetValuesForKeysWithDictionary (animDict);
        theAnim.Duration = 2;
        theAnim.StartAnimation ();

然而，在运行应用程序时，我得到了以下运行时错误: 2011-05-08 00:53:30.827下一集61715:613:这个类与键NSViewAnimationTargetKey的键值编码不兼容。

知道我做错了什么吗？谢谢！

Answer 1

不能使用SetValuesForKeysWithDictionary方法将动画关键点传递给NSViewAnimation实例。

必须使用NSViewAnimation(NSDictionary[] viewAnimations)构造函数来传递动画字典。

Answer 2

//为第一个视图创建属性字典。

        NSMutableDictionary firstViewDict = new NSMutableDictionary ();


        //var firstViewRect = new NSDictionary[] { };
        firstViewDict [NSViewAnimation.TargetKey] = animateWindow;
        firstViewDict [NSViewAnimation.StartFrameKey] = NSValue.FromRectangleF (new RectangleF (1000, 300 , this.Frame.Width - 40, 0));
        firstViewDict [NSViewAnimation.EndFrameKey]  = NSValue.FromRectangleF (SettingNSWindow.Frame);


        //var NSDict = new NSDictionary[]{ };
        NSDictionary[] NSDict =  new NSDictionary[]{firstViewDict};

        //NSDict.Cast(NSMutableDictionary = (NSDictionary[])firstViewDict;

        NSViewAnimation theAnim = new NSViewAnimation(NSDict);

        //theAnim.SetValuesForKeysWithDictionary (firstViewDict);
        theAnim.Duration = 2;
        theAnim.StartAnimation ();
